CHARLES WESLEY BATES, OF ST. HYACINTHE, QUEBEC, CANADA.

SEATING-UP MECHANISM FOR LOOMS.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed March 10, 1905. Serial No. 249,453.

To all whom it may concern.-

Be it known that I, CHARLES WEsLEY BATES, of the city of St. Hyacinthe, Province of Quebec, Canada, have invented certain new and useful Improvements in Beating- Up Mechanism for Looms; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates particularly to looms for Weaving textile fabrics and it has for its object to provide more efficient means for moving the weft-thread into position in contact with the woven cloth during the operation of weaving.

The invention may be said, briefly, to consist of a comb and means whereby such comb is caused to vibrate in a path wherein it in terdigitates with the warp-threads behind the newly-placed weft-thread, then advances and moves the latter into contact with the woven cloth, then recedes and drops out of engagement with the warp-threads and behind the line in which the neXt Weft-thread will be placed.

A further feature of the invention is a stationary reed for supporting the shuttle as it is shot from side to side of the loom, such reed being of sufficient width to accommodate the comb in its operation and being disposed with its wires a corresponding distance apart to the teeth of the comb and interdigitating therewith.

For full comprehension, however, of my invention, reference must be had to the accompanying drawings, forming a part of this specification, in which like symbols indicate the same parts, and wherein Figure 1 is a vertical sectional view taken on line A A, Fig. 2, and illustrating a portion of a loom provided with my invention. Fig. 2 is a horizontal sectional view thereof, taken on line B B, Fig. 1; and Figs. 3 and 4 are detail perspective views of my improved comb and reed.

The frame I) of the loom, the manner in which the cloth-roll c, breast-beam d, the brackets a (one only of which is shown) for supporting the harnesses f f are mounted in the same, together with the crank-shaft g, are ofordinary construction, and I will not describe the same in detailj The preferred embodiment of my invention comprises a comb consisting, preferably, of a round bar it, having a series of teeth or fingers Z set rigidly in one side thereof, such comb being adjustably carried by a pair of vibratory pitmen 'm, by means of which, in conjunction with a pair of guiding devices and a shuttle-raceway of novel construction, it is caused to move forward the weft-threads so that immediately they are delivered they are placed into contact with the Woven cloth.

Isecure the comb adjustably to the pitmen, preferably by means of two pairs of vise-jaws o 0 and p p, the said vise-jaws 0 0 being each formed with a tailpiece g and such tailpieces being bolted, as at r, to the tops of the pitmen a sufficient distance from the ends thereof to enable the base of the jaws to be supported thereon. The upper portions of the adjacent faces of the jaws are formed with semicircular recesses S, adapted to receive the bar 7c of the comb between them, and the lower portions of such adjacent faces are similarly recessed, as at t, to receive one end of a stub-spindle a, the opposite end whereof has an antifriction-roller 22 mounted thereon, while such jaws are clamped together by bolts to and nuts 11;, upon tightening which the c 1nnb and stub-spindles are rigidly held in ace.

p The shuttle-raceway I prefer to use consists of a rigidly-mounted horizontal reed comprising a pair of side frame-bars 2 and 8, the former of which is of trough crosssection and the latter an angle-iron, the wires 4 of such reed being soldered at one end to the side edge of the bar 2 and at their other ends to the angle-iron. This reed is supported in a bracket 5, bolted, as at 6, to the frame of the loom and consisting of a pair of horizon tal portions 7, to which the reed is secured by bolts 8 and clamping-plates 9, and a pair ofsubstantially C-shape portions 10, the lower ends whereof are formed integrally with the horizontal portions 7 and the depressions whereof receive the trough-shape side bar 2 of the reed, while the groove of the latter re ceives the lower side bar of the usual vertical reed 12.

The transversely-slotted raceway constituted by this rigid reed enables the comb to enter between the warp-threads at a point behind the path along which the shuttle travels on the raceway, thereby making the engagement thereof with each weft-thread certain.

The guiding devices I prefer to use consist of a pair of vertically-arranged plates 20, each formed with a slot presenting portions 21 and 22, extending substantially parallel to the reed and in different horizontal planes. The antifriction-rollers 1) run in these guideways, and the portions 21 of each of the latter are located far enough below the reed to cause the comb to sink out of engagement therewith, and the portions 22 are at a height adapted to cause the top of the teeth or fingers of the comb to project above the surface of the reed and above the level of the weftthreads as they lie thereupon, while the incline 23 in each guideway is located at a point to cause the comb to rise to its engaging position at a point behind the delivered weftthread. Each slotted plate is supported upon a pair of legs 25, bolted, as at 26, through slots therein to the machine-frame b.

In the operation of a loom provided with my invention immediately the shuttles have placed each weft-thread upon the reed the comb will rise up behind the latter and move it into contact with the woven cloth, (indicated at :10.) Such comb will then recede and sink down from intersection with the reed and warp-threads, and the operation is re peated.

The shuttleboxes 30 are constructed eX- actly as formerly, except that they are secured, as at 35, rigidly to the frame of the loom, one at each end of the shuttle-raceway.

What I claim is as follows:

1. In a loom the combination with a device adapted to move the weft-thread into contact with the woven cloth, of means for intermittently operating such device, stationary guiding mechanism whereby the said device is disengaged from the warp-threads during each period of intermission.

2. In a loom the combination of a pair of stationary guiding devices one at each side of the loom and presenting connected guiding portions in different planes relatively to the warp-threads, a vibratory device for moving the weft-thread into contact with the woven cloth, and a pair of lateral projections upon such device and engaging such guiding devices for the purpose set forth.

3. In a loom the combination with a vi-. bratory device for moving the weft-thread into contact with the woven cloth, of a pair of stationary guiding devices one at each side of the loom and each formed with a slot presenting connected guiding portions in different planes relatively to the warp-threads, a

pair of lateral projections upon such device one at each side of the loom and engaging the said slotted guiding devices, for the purpose set forth.

4. In a loom the combination with the shuttle-raceway, of a comb for beating up the weft-thread; means for imparting a beating-up action to the comb and means whereby the said comb is enabled to enter between the warp-threads at a point behind the path along which the shuttle travels on the raceway.

5. In a loom the combination with a transversely-slotted stationary raceway, of a device having fingers adapted to be projected through the slot of the raceway, and means imparting to the said device movements alternately from one side to the other of the tread of the raceway and transversely through such tread.

6. In a loom the combination with a stationary raceway in the form of a reed, of a device having fingers adapted to be projected between the wires of the reed and means imparting to the said device move ments alternately from one side to the other of the tread of the reed and transversely through such tread.

7. In a loom the combination with a stationary reed adapted to act as a raceway for a shuttle, of a vibratory device for moving the weft-thread into contact with the woven cloth such device having projecting members adapted to intersect the reed and having a pair of lateral projections one at each side of the loom, a pair of stationary guiding devices one at each side of the loom and each ar ranged to be engaged by one of the said projections, such guiding devices presenting guiding portions out of parallelism with the warp-threads, for the purpose set forth.

8. In a loom the combination with a stationary reed adapted to act as a raceway for a shuttle, of a vibratory comb for moving the weft-thread into contact with the woven cloth and the teeth whereof are adapted to intersect the wires of the reed, such comb having a pair of lateral projections one at each side of the loom, means for vibrating such comb, a pair of stationary guiding devices one at each side of the loom and each arranged to be engaged by one of the said projections, such guiding devices presenting guiding portions out of parallelism with the warp-threads, for the purpose set forth.
